The last thing you want during a sunny park session is blinding light obscuring your vision, especially when you're dialing in new tricks and sending bigger jumps. Eliminating distracting glare on the sunniest days of the season, the Anon M3 Polarized Goggles feature a polarized smoke lens for optimal clarity when you're lapping the park and riding powder on bluebird days. The M3 Goggle boasts Anon's Magna-Tech interface with 18 rare earth magnets, allowing you to quickly and securely swap lenses without the prying and twisting you've come to associate with traditional goggles. It's sporting Anon's Magnetic Facemask Interface, which seamlessly attaches to Anon's MFI facemask (sold separately) with four magnets along the bottom of the goggle's frame. This is a great feature if you're seeking gap-free protection when it's howling like a hurricane on the mountain. Besides the magnetic lens swapping and facemask attachment, the M3 features a classic cylindrical shape and frameless design, both of which offer a large, unobstructed field of view.
